Features
- Metering: It has the function of time-sharing metering, and the active electric energy is accumulated according to the corresponding time period, and the total, peak, peak, flat and valley electric energy is stored.
- Prepayment: The watt-hour meter can sell electricity through the remote 485 or LORAWAN/NB module. When the electricity quantity is lower than the alarm value, the user is reminded to purchase electricity in a display mode; It has the function of overdraft limit.
- Measurement and monitoring: It can measure, record and display the voltage, current, power factor and other operating parameters of the current watt-hour meter. The measurement error shall not exceed ± 1%.
- Timing function: Built-in hardware clock circuit with temperature compensation function is adopted, which has automatic conversion functions of calendar, timing and leap year.
